The swith is located just under the rubber between the rain sensor and the roof. The wires keep the swithc in place, but you can use glue. As I said before we can connect to power of the remote to the 12 V of the car, This mod is available with the DIY - Clown nose blinking LED. But if you are leasing the car, it's better to change to battery once a year!

The small switch or any other swith can be found at a specilazed spare electronic store, probably at Radio Shack. If you don't fin one, try to get one from an old electronic device like the reset switch of an old computer.

The new switch needs to be connected with the wires to the connections of the actual remote switch.
